How can I apply naive Bayes classifier for three classes (Positive, Negative and Neutral) in text data?
Use TextBlob to get the text sentiment polarity and subjectivity. polarity is negative or positive sentiment and subjectivity is how factual the sentiment is.
my_valance=TextBlob(sentence)
df.loc[key,'sentiment_polarity']=my_valance.sentiment.polarity
df.loc[key,'sentiment_subjectivity']=my_valance.sentiment.subjectivity
